From afad68b114e5ca82e1895b2df29d06086fa3ec67 Mon Sep 17 00:00:00 2001 From: m3ultra Date: Fri, 17 Jul 2026 17:21:34 +1000 Subject: [PATCH] =?UTF-8?q?Lane=20D=20R28=20(v5.1):=20instrument=20LOD=20?= =?UTF-8?q?=E2=80=94=20KILLED=20with=20the=20measurement=20(ledger=20#4)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit E: STOP — do not build the _lo variants. That work is unnecessary; the item is dead. The oldest tri item on the books, killed under the wind-sway rule attached to the brief ("if the measured win is <20k tris in practice, KILL it with the measurement"). MEASURED, from the shipped depot GLBs: each of the five instruments is exactly 14,000 tris; band + amp on stage = 70,000. On paper a 3-4k _lo each "saves" ~52k, clearing the 20k bar easily. But the rule says IN PRACTICE, and the brief named the reason — "interiors are close-quarters". So I measured the rooms an LOD would have to fire in (live, all three venue archetypes, interiorMode driven by hand since rAF is throttled): pub 9.7 x 9.7m, diagonal 13.7m, 12522 tris, 38 draws band_room 8.9 x 9.6m, diagonal 13.0m, 11699 tris, 35 draws rsl 12 x 9.4m, diagonal 15.2m, 15115 tris, 38 draws (the biggest) VERDICT: practical win = 0 tris. A player can NEVER be more than 15.2m from the band — corner-to-corner in the largest venue, and the stage sits at one end so the real max is shorter. An LOD is a distance trade; inside a <=15.2m room the band is never small — it is the subject of the gig and of F's tour money shot. Any sane threshold (15-25m) never fires; an aggressive 8m one fires in half a room at a distance where a 3-4k _lo is visibly worse with no perceptual cover. The win isn't "small", it's STRUCTURALLY ZERO — the distance an LOD needs does not exist in this game. Off the backlog forever. No budget motivates it either: a venue interior is ~12-15k tris, ~85k with the band — inside the 200k stress ceiling E's R22 tri diet restored, at 35-38 draws vs <=350. SIDE-OBSERVATION for E (not a proposal, no breach motivates it): all five instruments are EXACTLY 14,000 tris — a decimator target, not a measurement of the objects. A mic stand does not need 14k. If instrument tris ever do drive a real breach, the lever is a flat re-decimation by object complexity (mic stand -> ~1k), which beats any LOD because it needs no distance. Filed so the next tri hunt starts from it. Spike 1 (ledger #1) pending E's lean.glb — look.glb has landed, lean.glb not yet.
